Step 1: Open Regedit (Windows Registry Editor).
Step 2: Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\ESET\ESET Security\CurrentVersion\Config\PluginState\Settingset\Settings\SCANNERS\*
The exact path varies slightly by product.
Step 3: Look for a value named Settings000 or Password or Passwd. Values are binary or REG_SZ.
Step 4: Copy the hex data or base64 string. eset password decoder
Step 5: Use a known decoding algorithm (Python example for older ESET version):
import base64
def decode_eset_password(encoded):
# Simplified example: ESET v7 used XOR with 0xAB on base64 decoded bytes
decoded_bytes = base64.b64decode(encoded)
password = ''.join(chr(b ^ 0xAB) for b in decoded_bytes)
return password
Modern versions (v12+): The algorithm now includes a rolling XOR key derived from a static salt, making manual decoding trickier but not impossible with open-source tools.
This tool is intended only for recovering your own lost ESET passwords from configurations you legally own. Unauthorized decryption of passwords without explicit permission violates ESET’s terms and computer misuse laws. Always maintain proper access control.
An ESET password decoder is a software tool, script, or manual process that reverses the obfuscation algorithm used by ESET to store protection passwords. Its purpose is to extract the original plain-text password from the encoded string found in the registry or configuration files. Step 1: Open Regedit (Windows Registry Editor)
Over the years, several utilities have emerged to address this need:
| Tool Name | Version Support | Status | |-----------|----------------|--------| | ESET Uninstall Password Finder (EUPF) | ESET v4 – v6 | Discontinued | | ESET Password Decoder by ‘NSC’ | v5 – v9 | Legacy | | ESET Registry Password Decoder (PowerShell script) | v7 – v10 | Community maintained | | EsetPassDecoder (open source on GitHub) | v7 – v13 | Active (as of 2024) | | ESET Config Dumper + Decoder | v10 – v15 | Commercial tools |
Modern ESET versions (v13+) have slightly altered their obfuscation technique, meaning older decoders (from 2015) will no longer work.
If you are uncomfortable with third-party decoding tools, consider these alternatives: The exact path varies slightly by product
If the device is enrolled in ESET PROTECT, an administrator can push a policy that clears the local protection password. No decoding needed.
Recover saved passwords from ESET products (e.g., ESET Endpoint Security, ESET File Security) when stored in encrypted form inside settings.xml or registry entries. Useful for IT admins or users who lost their ESET management password but still have access to the configuration file.
A: Use a password manager (e.g., Bitwarden, 1Password). Store the ESET recovery PFX file in an encrypted cloud folder or offline USB drive.
